LUB'RICATING DEVICE FOR ENGINES.

SPECIFICATION forming part of Letters Patent No. 397,293, dated February5, 1889.

Application filed A t 4, 1888. Serial No. 281,944. (No model.)

To all whom it may concern:

Be it known that I, ALBERT L. IDE, of Chicago, in the county of Cook andState of Illinois, have invented certain new and useful Improvements inIntbricating Devices for Engines; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, and to the letters of referencemarked thereon, which form apart of this specification.

This invention relates to improvements in steam, gas, or other engines,and more particularly to improvements in lubricating devices for thecrank-shaft, connectingrod, cross-head, and other parts of such engines.

The invention consists in the matters hereinafter described,'and pointedout in the appended claims.

The invention is herein shown as illustrated in connection with ahorizontal sta tionary engine of that class having two crankdisks; butthe main features of the invention may be applied to engines of uprightor other forms and to other than stationary engines.

The engineframe herein shown is similar in its general features ofconstruction to the frame illustrated and described in a separateapplication for patent, Serial No. 213i, 607, filed February 20, 1888.

In the said drawings, I igui-e l. is a longitudinal section of an engineand frame illustrating my invention. Fig. 2 is a detail section of thesame, taken upon line 2 2 of 1. Fig. 3 is a detail section showing amodification of the lubricating devices illustrated in Figs. 1 and Asillustrated in the drawings, A is the engine-cylinder, and B isahorizontal continuous frame or bed supporting the bearings of thecrank-shaft at one end and the cylinder A at its opposite end, thecylinder being socured to the extreme end of the frame, so as tooverhang the latter.

O is a crank-shaft, which has bearings 19 Z) at one end of the frame 13.Said shaft 0 is provided between the bearings b b with twocrank-disks,(l C, in which is secured a crankpin, C

D is the piston-rod of the engine, which is attached to a cross-head, E,which is held in guides F F, formed upon the engine-frame. Saidpiston-rod connected with the crankpin (3 by means of a connecting-rodG, in the usual manner.

The engine-frame B contains certain novel features of construction, asset forth in said separate application, Serial No. 264,607, hereinbeforereferred to. Said frame is provided with an overhanging cylindric part,b, to which the cylinder is attached, and the lower part of the frame isformed by a hollow base,

8. The main or upper portion of the frame B adjacent to the cross-headguides F F is tubular, and the lower wall of said tubular part of theframe is extended from the lower cross-head guide to form a wall, Bwhich slopes downwardly beneath the crank-disks to the level of thebottom of the frame, the bearings b I) being supported by walls Bforming extensions of the side walls of said tubular part.

B", Fig. 1., a vertical wall extending rearwardly from the side wall, Band united with a transverse end wall, B connecting the said side wall Bwith the corresponding side wall at the opposite side of the frame. Saidend wall, 13 is located at the end of the frame exterior to thecrank-disks C C, and forms, with the side walls, 13 and B, and thebottom wall, B, a basin or tank, B for con taining a quantity of oil orother lubricant, in which the peripheries of the crank-disks areimmersed when the engine is running.

H is a removable cover, which is fitted to the adjacent margins of theside walls, B and B, the end wall, 13 and the adjacent margin of thetubular part B of the frame, and is shaped to completely inclose orcover the crank-disks O C. Said cover H serves to protect from dust anddirt the several mov ing parts within the f nine, as set forth in saidseparate application, and also serves, in connection with theengine-frame, to form a casing or housing, which operates, in connectionwith lubricating devices constructed as herein shown and claimed, to aidin supplying lubricant to the several bearings of the engine.

In the use of an engine-frame constructed to form a housing or casingwhich entirely incloses and surrounds the crank-disks and the cross-headguides, and which is provided in its lower part beneath the crank-diskswith an oil-tank, B as shown and described, the crank-disks, when turnedin a direction to carry theirlower parts or surfaces toward theengine-cylinder, act to take up and throw forward, mainly toward thecylinder, but also into other parts of the housing, drops or particlesof the oil or other lubricant contained within the said receptacle B asindicated by the arrows in Fig. 1. The drops or particles of oil orlubricant thus thrown or cast upwardly and i'orwardly by the cranlediskswill be distributml throughout the interior of the casing or housing andserve to afford a con-i tinual and abundantsupply of lubricant upon thesurfaces of the eross-l'ieml guides, and will commonly afford asultieiently abundant supply of lubricant tothe pivotal connectionbetween the connecting-rod and the piston.

The cross-head illustrated in Fig. 1 is generally similar to that shownin a prior patent, l\'o. 321,726, dated July 7, 1885, said crossheadbeing hollow or of boxtorn1,and. eons" ting of a rectangular main part,I, in the side walls of which a wrist-pin,1, is supported, and.bearingplates I l attached to the upper and lower surfaces of the mainpart of the eross-heml. and directly engaging the guides.

In the eonstructit'm shown in Fig.1 the upper horizontal plate or wall,1', ofthe main part 1 ot' the hollow cross-head is provided in itscenter with a depending conical or tapering projection, 11, which islocated over areceptacle, g, placet'l upon the end of theconiu'zeting-rod t, and communicating by a passage, g, with thel)(atring-suriaee ol the crankpin I. In a construction of this kind theoil thrown by the action of the revolving crankdisks upon the undersurface of said plate 1", or flowing to the under surface of the saidplate as it is scraped from the upper crosshead guide, 1!, by the plate1 will drop from the end of the projection 1 and thus enter thereceptacle q, I'rom which it will flow to the bearing-surl'ace ot' thewrist-pin, thereby atl'ording an abundant supply olf lubricant to thesame.

The head G of the eonnecting-rod is provided with an oil cup orreceptacle, 5 which communicates with the bearing-surface of the brassestherein by means of a passage, g", said cup or receptacle in thisinstance being preferably elongated in the direction of the planes oithe crank-disks. Upon the under surface of the upper wall of the coveror housing II: is formed a depending serrated flange, N, having at itslower end a series of teeth or points, /1 )2, arranged over and in thesame vertical plane with the oil cup or receptacle The said serratedflange N may of course be replaced by a series of separate points ordepending nojections. In the operation of the device thus constructed aconsiderable portion of the oil thrown upon the under surface of thecover or housii'ig will flow downwardly upon and drip from the ends ofthe teeth or projections 11 n, and the oil thus dripping or falling fromsaid projections will be caught by the said receptacle as the crank-pinrises in the revolution of the disks, thereby allording a continuoussupply ol. lul'u'iez'int to the said receptacle for supplying thecrank-pin.

In Fig. 3 is shown a eonsta'uetion substantially similar to that inIiigs. '1. and 2, with the exception that two rows of teeth orprojections, II n, are employed, which areadapteul to supply oil to twoseparate oilcups, q", upon the connectingrod head. 'lhis eonstrnetionwill be uselul in case of that form olf head illustrattal in said Fig.33, wherein the head is n'iade-in two parts connected by bolts, insteadof being provided with brasses held upon the main part olf the rod by astrap, as illustrated in l igs. and L. p

.I, Fig. i], is a trough or reeept'acle extending across the rear endof: the wall of the covering or housing II, so as to receive thelubricant cast upon and running down the under surface ol? the rear partof the said cover II. This trough is connected with a pipe or tube, .l,provided with a valve, j, and arranged to discharge into an oil-cuplocated upon crankshai'tbearing. 'lhese :teatures ott' construction areshown and claimed in a separate application for patent, Serial No.itfitJlOS, tiled by me in the United Statcslatent Otliee February 20,1838.

My invention embraces as one of its main features the combination, withan oil-tank containing a luln-ieant in which the crank disk or disks areimmersed and turn, and a housing su rronnd ing said disks provid ed withtltlpfllltl in pointed projections, of a receptacle placed beneath said'iointed projections to receive oil delivered to the said interiorsurface ol the housing and dripping or flowing from said pointedprojectim'is, and a passage or passages connecting said receptacle witha surface to be oiled or lubricated; and I desire to claim thisconstruction broadly as applied to the oiling of any moving parts of theengine, it being entirely obvious that the same 1i rinciples ofconstruction and operation maybe employed for oiling stationary andother betn'ings as is used in oiling the crankpin and the wristpin inthe engine herein illustrated.

I have herein shown the casing or housing surrounding the disks andother operative parts as being formed partially by the engine-lranie,which. is made of peculiar form for this purpose, and. partially as.t'ormed in or by the frame itself. As far as the operation of thelubricating device described and broadly lftlll'ltitl is conem'ned,however, itwill be readily seen that said tank may be separated from theframe and that an inclosing easing or housing for the operative parts ofthe engine maybe made otherwise than as above set forth. I do nottherefore wish to limit my invention to a construction in a ho'usin oreasing formed partially by the enginc-t'ranw or to any other specificfeatures of construction in the said housing or casing itself, except ascertain novel features of construction. in said parts, hereinillustrated, may form the subject of specific -claims herein.

Certain novel features of construction in the particular lubrieatin gdevices illustrated are herein specifically claimed as separateimprovements in addition to the main features of the invention above setforth.

I claim as my invention 1. The combination, with an engine cra'nk- 1shaft and a crank-disk connected therewith, of a casing or housingsurrounding the disk, having an. oil tank or basin beneath said disk,said casing or housing being provided with a depending pointedprojection, b y which the oil flowing from the inner surface of thecasing or housing may be directed orcarried to a part to be lubricated.

2. The combination. of an engine crankshaft, a crank-disk connectedtherewith, and a housin or casing'surrounding the disk and provided withdepending pointed projections upon the said housing or casing, andhaving an oil tank or basin beneath said disk, an oi l- .receptaclesecured to the coiniecting-rod and arranged beneath saidpointedprojections, and having a pipe and a passage leading from saidoil-receptacle to the bearing-surface to be lubricated.

The combination, with an engine crankshaft, a crank-disk,connecting-rod, and cross head, of a casing or housing surrounding thedisk, connecting-rod,and cross-head, and hav- 1 ing an oil tank orbasin. beneath the disk, a wrist-pin in the cross-head engaged with theconnecting-rod, and an oil-cup upon the said connecting-rod communieating with the bearl eating with the bearing-surface of the wristpin, saidhollow cross-head being provided upon its upper wall with a dependingprojection located over the said oilcup, substantially as described.

5. The combination, with an engine crankshaft, a crank-disk, crank-pin,and connecting-rod, of a casing or housing surrounding the disk andhaving an oil tank or basin beneath the same, and provided with pointedprojections, an oil-cup upon the connectingrod communicating with thebearing-surface of: the crank-pin, said pointed projections dependingfrom. the top of said housing or casing over the oil-cup for the purposeof deliv ering to the said oil-cup oil thrown upon the housing by thedisk, substantially as described.

In testimony that I claim the foregoing as my invention I affix mysignature in presence of two witnesses.
